摘要

Dou-Gong is one of the key factors in achieving seismic resistance and energy dissipation for timber architectural heritages. This study carried out experimental and numerical research to investigate the lateral hysteretic behavior of three typical Ming–Qing Dou-Gong: DouGong-PingShenKe (DGPS), DouGong-ZhuTouKe (DGZT) and DouGong-JiaoKe (DGJ). Quasi-static cyclic tests were conducted to obtain the failure modes, hysteresis curves, and seismic performance parameters. The results indicated that all specimens exhibited significant sliding and pinching effects, with DGZT and DGJ demonstrating better energy dissipation capacity. Based on the experimental data, refined finite element models were developed and validated, from which the force flow paths were extracted to establish a simplified model. The experiment results can provide a crucial basis for understanding the seismic mechanism of Ming-Qing Dou-Gong, and the simplification method can offer an efficient and reliable tool for the seismic performance evaluation of timber architectural heritages.
